Pulp and paper producers would profit enormously from an advanced knowledge of the physical and mechanical properties of a fibre product based upon a measure of the pulp while it is still in process. This project aims to develop such a tool. Using a laser backscattering technique called Raman spectroscopy, will calibrate the molecular bar code it reads from an in-process pulp to accurately predict the properties of a paper or other fibre products that can be made from that particular pulp.
